[ovirt-users] ovs-vswitchd high cpu usage

[Arnaud Lauriou]

Hi,

Just updated last week ovirt hosts from 4.0.6 to 4.1.1 and I noticed 
ovs-vswitchd
high cpu usage, around 100%.

My cluster switch type is in legacy mode, so I decided to stop 
ovs-vswitchd process
on each ovirt host.

This morning, when trying to run a new VM and I've got the following 
error message :
Exit message: (21, 'Executing commands failed: ovs-vsctl: 
unix:/var/run/openvswitch/db.sock: database connection failed (No such 
file or directory)')

Even if the cluster is in legacy mode, it seems that ovs-vswitchd needs 
to be up and running for vdsm.

So, how can reduce the cpu usage of ovs-vswitchd process ?

Regards,

Arnaud
